Hi,

I am researching possible solutions for a simple database application
delivered to a Pocket Windows PDA (PocketPC). The database will be a subset
of a larger company-wide database held on a Linux server using MySQL and
PHP.

The PDA database will be used by a small number of people - probably no more
than 10 initially - and they will make only a small number of edits to the
database, fewer than 5 daily under normal circumstances.

The server and database already exist, so no configuration changes are
possible, but I can make changes to the database if required.

I'd love data replication with the server to be automatic if possible, but
if I have to build something to handle that then so be it.

For the sake of a nice clean, updatable interface, and to allow for some
other multimedia facilities which we can consider unrelated to this
database, the interface will be Macromedia Flash.



I am looking for the least painful method to enable the above. I have
encountered numerous suggestions including

- Wrapping the Flash interface inside a eVC wrapper, eVB, e.Net (C#) ...
- Using a local Access database, synchronising that with a server copy and
then synchronising the server copy of the access database with the main
MySQL application.
- Saving a record of local updates to text/xml file then passing the saved
data to the server for processing on synchronisation. If user A makes
updates, a record of those updates is then saved to a special table for
users B, C, D ... so that when they synchronise they can download and apply
the same edits. ..... but an automatic replication would be far more
elegant.


So far all of this is speculation. Obviously I have to make a choice as to
what methods I will apply and what technologies to employ. Has anyone here
done anything similar to above? Can you share comments, suggestions, tools
used?


TIA


Steve
